The combustion of propane, C3H8, a fuel used in backyard grills and camp stoves, produces carbon dioxide and water vapor. C3H8 (g) + 5O2 (g) - > 3CO2 (g) + 4H2O (g) What mass of carbon dioxide forms when 95.6 g of propane burns?

286.8g of carbon dioxide forms when 95.6g of propane burns. The total atomic mass of the propane is 44 (g). The total mass of the carbon dioxide formed when 44g of propane is burnt is 132 (g). 44 divided by 44 equals 1. 132 divided by 44 equals 3. Therefore the amount of propane to carbon dioxide is in a 1:3 ratio. Therefore, 95.6 multiplied by 3 gives you the amount of carbon dioxide formed.
